To all fwho-m 'it'may concern: o l

Be it known that I, KARL O.. OLSON, a citizen of the United States, residing at Chicago, in the county ofCook and State of Illinois, have invented certain new and )useful -Improvements in Apparatus for Inserting Closures in Vessels; and I do hereby declare theJ following to be a full, clear,I and exact description of the invention, such'as will enable others skilled in the art to which it appertains to make and use the same. This invention relates to means for closing receptacles and has for its object toproduce a device of this nature which willmore effectually insert the inverted flanged cupshaped closures into the mouths of paper vessels than the means at present employed.

To these ends the invention consists in the novel details of construction and combinations of parts, more fully hereinafter disclosed and' particularlypointed out in the claims.

Referring to the accompanying drawings, forming a part ofI this specification, in which like numerals refe;l .to like parts in 'all the views Figure 1is a diagrammatic eleva- Jtional view partially in section of the well known die plunger press adapted for inserting closures in paper vessels, with my improvement attached thereto; Fig. 2 is a plan view of that portion of the mechanism shown vin Fig. 1 lying below the line 2-2';

' portions ofthe mechanism'shown in Fig. 1,

2, a die cutting plunger 3, and adie shaping' plunger 4.

l5 represents the paper which is fedby suitable means underneath the plungers 3 and 4, and 6` the vertically -movable `ring shaped die through which the flanged disk closure? is forced by the plunger 4, all as isjnow well known.

The vertically movingring 6 which for brevity I will hereinafter call a loating'ring,

is supported by suitable springs 8 and guided as bythe rods 9 through suitable guide lugs Fig. 3. is a sectional elevational view of the essential- 10 integral. or otherwise attached tothe framework 117 provided with a. beveled ring shaped portion 13, terminating-in the overhanging lip This floating ring is also 14. The beveled portion 13, as the floating i ring descends, surrounds and accurately shapes to a circle the upper edge 15.. of the vessel 16 to be closed; while the overhanging I vlip 14 projects over and protects the said upperl edge 15 of the body Vof the Vessel 16 from being crushed during the inserting operation, as plainly appears 1n Fig. 3. It

results from this construction, that frangi# ble paper bottles may bereadily closed at a rapid rate by machinery without crush-l ing the same, and the mechanism so far disclosed constitutes no part of my present in-` sure 7. The bottle body 16 is so light and this friction is so great that as the plunger 4 beings -to ascend it is liable to carry the bottle body and ring 6'with it. This action is greatly aided by the springs 8 which automatically lift the. ring and' impart to it a tendency to follow the plunger upward.

Should the bottle 16 lift as indicated, it

results that it is removed from its seat on its support 18 and thereby disarranged for other operations which it may be desired to Aperform on it.

' In order to avoid this defect, I provide the Y floating ring 6 with the projections 20 and 21, preferably in the-form of pipes, in order that a liquid may be passed therethrough, as indicated, and I cut slots 22 and 23 in the framework 11 in order to permit the pipes 2O to move up jand down with the oating ring 6.- To the outside of the framework 11 I preferably pivot as at 25, a lever 26, having thehook 27 adapted to pass over one of the projections as 20, when the latter is in its lowest position, as best indicated in Figs.`

3 and 4. The spring 28 may be employed to automatically return thelever 26 into the position shown in Fig; 4,- after it has been displaced from such in Fig. '5.

The lever 26 is provided ,with an extension position, as indicated 31 having theslotted lug 32 the slot 33 of which plays a pin. 34 attached to the reciprocating rod 30 secured to the cross headslot 33 just after the floatingl ring-6 has d e-. scended to its lowest position, and the said pin 34 will thereupon, cause the hook 27 to take over and to firmly lock in place the pipe 20, as indicated in Fig: 3, thereby holding the Heating ring 6 in its lowest position. When the cross head 2 now ascends the pin 34 will rise in the slot 33 and will strike the upper end Aof the same after the plunger has left `the mouth of the bottle 16 whereupon the said pin 34 will swing the hook-27 out of its locking position, and permit the pipe 2O andthe floating ring 6to rise into the position indicated in Fig. 1. This cycle'of operations is repeated over and over again.

It is; often desirable to coat at least a portion of the outer surface of the closure 7 with anv adhesive before inserting it into the bottle, and when this adhesive is applied to such closures the plunger 4 necessarily gets more or less gummed Vup therewith, and is, therefore, more liable to lraise the bottle body 16 and the ring 6 from its seat than would be the case were no adhesive employed.

My invention, therefore, is of peculiar importance when adhesives are used in connection"`with machinery for closing bottle bodies, for that it rmly holds the bottleV in position by causing the floating ring to act as a stripper no matter how much lthe friction may be between the plunger 4fand the inside of the bottle mouth.

In'the drawings, I have indicated a convenient means for applying adhesive to the closure 7 which consistsin openings in the fioating ring through which hot paraflin 'or other adhesive may be fed to the closure 7 `just prior to its lnsertion into the bottle body. The hot paraffin may be conveniently applied from a tank 41 connected with the pipe 21 by means of a iiexible connection 42, as illustrated. In order that the hot paraliin may not flow .out while the openings-40 are uncovered, I provide a suitable valve device 43 operated by a pm and slot connection 44 and a rod45 connected with the crosshead 2, as will be readily understood.' Paraffn, as is well known, is an eliicient I lubricant and it is also, when applied to paper and allowed to cool a most excellent adhesive.`

It therefore follows that no gumming occurs on the ring 6 andthe plunger 4 `when paraffin is used as the adhesive since it merely acts as a lubrlcant 11i-the o eration of the machine. In addition to this, when paper is paraffined, it is much more pliable and easily worked under a die press than is unparaned' paper. Therefore paraliin is peculiarly adapted for use as the adhesive in connection with this machine.

The parts 44 and 45 are so timed that the valve 43 is' opened an instant before the paper closure 7 reaches the'ports or openings 40 and it is closed just before the said closure7 passes the said ports 40. The head of hot paraliin in the tank'41 serves to readily force the same through the ports 4Q as soon as the valve 43 is opened.

The 'hollowed out portion ofthe ring'6 is preferably closed by an annular ring closure 47- which may be readily removed for the purpose of cleaning the ring, 6, as'by inserting a wrench in the holes 48, as'will be readily understood.

It is evident that those skilled in the art may vary the detailsv of construction and the arrangement of parts disclosed without departing from the spirit of my invention and, therefore, I do not wish to be limited to such features' except as may be required.by the claims. What I claim is x 1.
